Abstract (en)
A color filter substrate manufacturing method comprises the steps of forming a black matrix (2) on a support substrate (1) and forming a color filter (4) by an ink-jet system. An alignment mark (3) is formed within an effective display region. And, alignment is performed using the alignment mark in forming the color filter. The alignment mark is formed at the same time as the black matrix so that it is precisely located with respect to the black matrix. The distance from the alignment mark to the starting position of the ink-jet head is short.
